RESILIENT WHEEL.

Application filed June 21, 1913.

To all whom it may concern:

Be it known that I, MARION F. YOUNG, a citizen of the United States,residing at Plainview, in the county of Hale and State of Texas, haveinvented certain new and useful Improvements in Resilient Wheels, ofwhich the following is a specification.

This invention relates to resilient wheels and has for its primaryobject to provide yielding spokes, which will absorb the shock when thetire comes in contact with road inequalities.

Another object of the invention resides in the provision of a peculiarformation of tire which is associated with the spokes in such a manneras to allow the tire to be flexed when contacting with road inequalitiesso as to be capable of the resiliency common to the pneumatic tires.

()ther objects as well as the nature, characteristic features and scopeof my invention will be more readily understood from the followingdescription taken in connection with the accompanying drawings andpointed out in the claims forming a part of this specification.

Referring to the drawings :Figure 1 is an elevation of a portion of awheel constructed in accordance with my invention; Fig. 2 is a sectionalview taken on the line 2-2 of Fig. 1; Fig. 8 is a sectional view of oneof the cylinders disclosing the contents thereof; Fig. 1 is alongitudinal sectional view of one of the tread plates; Fig. 5 is a topplan view of the same; Fig. 6 is an elevation of one of the treadbracing elements; Fig. 7 is a cross sectional view taken on the line 77of Fig. 2; and Fig. 8 is a longitudinal sectional view of a modifiedform of tread plate.

In the drawings wherein is shown the preferred form of my invention thenumeral 10 represents a hub which is of the usual or any desired formand has radiating therefrom cylinders 11 which are preferably molded tothe outer periphery of the hub and have extending upwardly inparallelism on each side thereof braces 12 which are preferably of acylindrical configuration and have the outer ends thereof reduced andprovided with screw-threads which are engaged by the-nuts 14. The outerend of the cylinder 11 is open and has arranged thereover a cap orclosure 15 which has Specification of Letters Patent.

formed centrally therein an aperture 16 through which a spoke 17operates when pressure is exerted on the tire. The closure or cap 15extends over the open end of the cylinder 11 and is sleeved over thereduced ends 13 of the brace elements 12. In order to hold the cap orclosure 15 into engagement with the top of the cylinder 11, a ring 18 isprovided which has apertures formed adjacent the opposite edges thereofthrough which the threaded ends of the reduced portions 13 are passed,said threaded ends being engaged by the nuts 14 so as to hold the ring18 into engagement with the closure 15 for the purpose described.

Mounted within the cylinder 11 is a coil or spiral spring 19 which hasthe one end thereof in engagement with the periphery of the hub and theopposite end engaging the head 20 of the spoke 17 The head 20 has formedthereon an elongated shank 21 engaging over the inner end of the spoke17 and rigidly secured thereto in any suitable manner. The outer end ofthe spoke 17 has formed thereon external screw-threads 22 which engagewith the bifurcated detach able end 23 of the spoke, which is inconnection with the tire.

Mounted between the head 20 and the outer end of each of the cylinders11 is an auxiliary spring 19 which is provided so as to prevent theshank 21 from coming in contact with the cylinder 11 after pressure isexerted from the tire, as would ordinarily be the case by the pressureof the shock absorbing spring 19 which is compressed when pressure isexerted on the tire.

The tire which is embodied in this invention comprises a plurality ofsuccessive plates 24 which are hinged together, the op posite ends ofwhich are provided with corresponding eyes or knuckles 25 through whichis passed a pivot pin 26 so as to hing edly engage one with the other.The plates 24 are substantially U-shaped in cross section and everysecond one thereof is provided with a pair of ears 27 one of whichdepends on each side of the plate for engagement with the branches ofthe bifurcated end 23 as shown to advantage in Figs. 1 and 2 of thedrawings.

By providing the spoke 17 with the external screw-threads 22 it will beseen that when the coil spring 19 becomes slack, that each recessed asindicated at 29 so as to in sure a positive bracing of the tire on thespokes and at the same time allowing for the proper resiliency in viewof the fact that the elements 28 are formed from suitable spring steelso that the same will yield to a certain extent when pressure is exertedon the outer periphery of the tire.

"The modification as shown in Fig. 8 discloses the usual tread plate 2&which is of an arcu'ate configuration andhas seeured to the outer facethereof a suitable elastic material 30 preferably rubber which willserve to further absorb the shock and is especially adapted for use onvehicles'of the lighter type where the pressure exerted on theperipherythereof would not beso great.

' In use the springs 19'are inserted in the cylinder 11 and the, cap orclosure 15 arrangedzover the top of the open endthereof, landsecurelyheld in place by the retaining ring l8-iwhich is provided withcut-out; por- 3O tionsat intervals thereon so as to be readily engagedover the cylinder. The head 20 of the spokel'? is engaged with the outerend of:the spring19: as shown to advantage in Fig. 3, and the spoke 17extending outwardly through the aperture 16 of the closure 15 so astoallow for the free reciprocation of the .head20 in the cylinder 11-when pressureis exertedon the outer end of the spoke. The spoke 17 ispreferably tubular so! asto reducethe weight of the tire to a minimumand has the detachable end 23 thereofrpivotallyengaging the tire 24.

From the above it'is obvious that when pressureis exerted on theperiphery ofthe wheelthatthe heads 20 of the cylinder 11 will'bedepressed inwardly in the cylinder, and automatically drawn outwardly totheir normal position as soon as the pressure is released.

It will beunderstood thatthe above description andaccompanying drawingscomprehendonly the general'and preferred embodiment of my invention andthat'various minor.v changes: in details of construction, proportion andarrangement ofthe parts maybe madewithin the scope of the appendedclaims and: without sacrificing any of the advantages of my invention.
